Description
Pcard-67164
This PR add ShapeOrDataDimExpr represent for TensorArray type.
Design note
TensorArray can append tensors dynamically during the execution of a computation graph, so we can't get a static Shape represenation of TensorArray. However, we can still record the shape of one element tensor as a hint, which can already provide some useful information for subsequent processing, since the elements in TensorArray most likely have the same rank and certain dimensions may have equal constraints.
